LASTING-MACHINE.

Specification of Letters Patent.

Patented Au Application filed March 26, 191 Serial No. 827,317.

To all whom it may concern:

Be it known that I, ERAs'rUs E. WINK- LuY, a citizen of the UnitedStates, residing at Lynn, in the county of Essex and State ofMassachusetts, have invented certain new and useful Improvements inLasting-Machines; and I do hereby declare the following to be a full,clear, and eXact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to lasting machines, and more particularly tosuch machines of the hand method type, and is an improvement on themechanisms and features of invention described and claimed in my priorLetters Patent of the United States, No. 1,057,606, granted April 1,1913.

It is desirable in lasting the better grade of shoes and in lastingshoes in which the pulling over operation has been ineflicientlyperformed, for the operator, in order to properly last the shank, toperform this step in the operation by hand. A spindle is commonlyprovided upon the bench at one side of the machine and prior to lastingone side of the shoe, the operator will spindle the last, seize themargin of the upper with hand lasting pincers, at a point about oppositethe ball of the last, and will then draw on the upper with a slow steadypull in a direction toward the heel and across the instep, such a pullbeing necessary to properly draw the upper at the instep to the wood.The upper at this point is generally slack and stands out from the bodyof the last owing to the sharp inward curvature of the last at the shankand a sharp quick pull which is sufficient to properly draw over theupper at the ball of the last, would not effectually draw over the upperat this point. After having thus stretched th upper and drawn it to thewood it is held tightly in place by the operator until the first tackhas been driven by the machine at about the ball of the last. After oneside of the shoe has been lasted, the last is again spindled, the marginof the upper at the opposite side of the ball of the shoe is seized byhand pincers at the instep and the upper is drawn to the wood bystretching it over that side of the last. A tack is driven at this pointand the remainder of the upper upon this side of the shoe is then astedas before.

The principal object of the present invat the shank may be readilyseized by the pincers, and then to assist the pincers to produce a longpull in lasting this portion of the upper.

Another feature of the invention contemplates the provision of improvedmechanism for driving the machine at speed slower than the normal speedduring the lasting operation at the shank whereby to obtain the desiredslow and steady pull on the upper at this point.

In accordance with this object, and such others as may hereinafterappear, as will readily be recognized by those skilled in the art, theinvention comprises the features,

.mechanisms and combinations of parts here inafter described andparticularly pointed out in the appended claims.

In the accompanying drawings illustrating the preferred form of theinvention, Figure 1 is an elevation of the ri ht hand side of themachine, the parts being shown, at rest, before an operation iscommenced; Fig. 2 is an elevation of the lower part of the right handside of the machine illustrating the driving mechanism, which, with.Fig. 1, forms a complete side elevation;

Fig. 3 is an elevation, in section, on the line 33 of h 1, lookingforward, this section line being shown as cutting through the drivingshaft at the point where the wedge for throwing in the slow speedmechanism is located, the rod for operating this wedge being broken awayand all the parts below it being omitted so as to show a por tion of theconnections for throwing in the high speed mechanism, the section linethen cutting through the frame of the machine at a point just below andforward of the high speed driving pulley; Fig. is an elevation, insection, on the line l-.4i of Fig. 1, looking forward, this section linecutting through the driving shaft just in the rear of the slow speedfriction clutch and through the frame of the machine a point below and alittle to the rear of this clutch,

sitions assumed by themechanism for looking the high speed drivingmechanism in its operative position; and Fig. 9 is a lon- I gitudmalsection on hne 99 of Fig. 3 of the wedge mechanism for connecting theslow speed friction clutch.

In the embodiment of the invention illustrated in the drawings, thelasting head, in so far as the lasting pincers and their operatingmechanism, the tacker and its tack supplying and operation mechanism,and other features relating to the conforming and securing of the upperin place are con cerned, may be, and preferably is, the same asillustrated and described in Letters Patent of the United States to S.W. Ladd and It. F. McFeely No. 584;,7H, and S. V. Ladd No. 597,321, towhich reference may be had for a full disclosure thereof, although it isto be understood that the features which are the subject of the presentinvention are capable of general application upon various types of handmethod lasting machines, and the present invention is not, therefore, tobe considered as limited in its use to the particular type of lastingmachine head shown in the drawings.

Referring to Fig. 1, the pincers are indicated at 1 and the tack driverat 2, the pincers being operated by trains of mechanism'leading to cams3 and 5 on the main driving shaft 6 (the rear portion only of thisdriving shaft being shown in Fig. l by dotted lines), the tack blockbeing operated by mechanism operated by cam 4c on said shaft, and thetack driver being operated by a cam (not shown) at the forward end ofthe driving shaft and a spring within the housing 7, all as illustratedand described in said Letters Patent hereinbefore referred to.

As hereinbefore stated, in many cases the shoe comes to the lastingmachine operative with its upper at the shank improperly fitted, so thatwhen the shoe is placed with its sole against the hold down 8 the upperis not in a position where the downward, or reaching, movement of thepincers can seize it. It is, therefore, desirable to provide means whichwill permitthe upper at the shank to be seized by the pincers whateverits length or its position relative to the last may be, and to this end,as in'myprior patent, means is provided for raising the 7 hold down asuflicient distance to enable the pincers to reach and seize allimproperly cut or fitted uppers. Such means will now be described and itwill be seen that the mechanism utilized to raise-the hold down is sodesigned that it may or may not be used, that is, if the operative findsthat the upper is so fitted that it is necessary to bring the shoenearer to the pincers than ordinarily, this mechanism can be thrown intooperation, and if'not thrown into operation the position of the holddownis not affected by the ordinary operation of the machine.

Referring now to Fig. l, the machine head has projecting forwardly fromits frame the usual bracket 9 for supporting the" hold down 8. Thisbracket has a depending part 10 at its outer end which part is providedwith a vertical guideway in which there is mounted a slide 11 (seedotted lines Fig.

1), the lower end ofwhich carriesa sleeve or housing 12 within which thehold down may be glven an in and out movement relative to the pincers.The hold down is provided on its upper side with a rack (not shown)engaged by the teeth of the segment 13 pivotally mounted on the slide 11and" having a substantially horizontal arm 14: projecting rearwardlythrough a slot in the part 10. The-outer end of this arm 1a is providedwith a ball and the arm is permitted a limited angular movement betweentwo vertically arranged, adjustable stops 15 carried by thedependingpart '10 of the bracket 9. The distance between the acting endsof the stops 15 determines the amount of movement given to the hold down8 within its housing 12, this movement being effected by a lifting ofthe slide 11 through mechanism now to be described.

The upper end of the slide 11 has pivoted thereto the lower end of alink 16, the upper end of which link is in turn pivoted to a horizontalarm of vertically arranged bell crank lever 17 fulcrumed on a lugprojecting from the bracket 9. 'The vertical arm of the bell crank 17has pivoted theretoone end of a' slide rod 18which extends rearwardlyand is guided by an aperture formed coiled about it an expansion spring20, one

'in a portion 19 of the frame. This rod has end of which bears'againstthe part 19 of tending lever 25 which, as shown in dotted V lines inFigs. 3"and 4, isforked and'hasa hub on the shaft 24 at each side of theshaft engaging hubof the lever 23. The free end of-the lever 25 carriesa cam roll 26 (Figs;

1 and 4:) which normally is held, by the spring 20, in contact with theplane, rear face of a cam disk 27 secured to the driving shaft just atthe rear of the cam disk 5 which controls the updraw movement of thepincers. Owing to the keyed connection of the lever 25 with the rockshaft 24 this lever can be slid longitudinally of said shaft to carrythe roll 26 outwardly from the driving shaft 6 across the rear face ofthe cam disk 27 to a position opposite a face cam 28 (Fig. 1) at themargin of said disk. hen this position is reached by the roll theexpansion of the spring which is then permitted will rock the shaft 24and seat the roll 26 on the plane surface 29 (Fig. 1) of said cam 28.Deferring until later the description of a further function of thespring 20, the means for sliding the lever along the rock shaft 24, andacross the face of the cam disk 27, will now be described.

Referring to the dotted lines in Figs. 1, 3 and t, it is seen that justbelow the rock shaft 24:, and extending at right angles thereto, is apivot rod 30. This rod has pivoted thereon a lever having two oppositelyextending horizontal arms 31 and 32 and a two part vertical arm 33. Uneof the hubs of the lever 25 is provided with oppositely disposedvertical grooves which are'engaged by pins, one in each of the free endsof the two parts of the arm 33. By means of this connection, when theurn 33 is moved angularly about its pivot 36, the lever 25 will be slidalong the rock shaft 24:. The means for moving the three armed leverangularly about the pivot comprises a link, or connecting rod 3% havingits lower end pivoted to the arm 31, and. its upper end pivoted. to aparallel arm 35 secured to the rear end of a rock shaft 36 extendingforwardly, parallel to the pivot rod 30, and journaled in bearings 37(Fig. 1) on the machine frame. At the forward end of the rock shaft 36,witnin convenient reach of the operative, there is secured a secondlever 38 in the form of a handle.

With the construction just described, in order to move the cam roll 26from its inacti ve to its active position it is only necessary for theo1 erative todepress the handle 38 which will turn the three armed leverin a dir ction to slide the roll 26 outwardly and then, as described,the expansion of the spring 20 will, through its thrust on the colar 21,move the slide rod rearwardly, to rock the shaft 2% and seat the rollonthe surface 29 of the cam 28 ready to be operated on by said cam whenthe driving shaft 6 is rotated. A further consequence of the rearwardmovement of the slide rod 18 is to rock the bell crank 17 about itsfulcrum in a direction to raise the slide 11 and with it the hold down8. As the slide 11 rises the end of the arm 14 will engage the upperstop 15 and turn the segment 13 in a direction to move the hold downoutwardly a short distance within its housing 12. The upward and outwardmovement of the hold down 8 is the same as described and illustrated inmy prior patent hereinbefore referred to.

After the, machine has been started the rotation of the cam disk 27 willcause the cam roll 26 to travel up the incline of the cam 28 and movethe slide rod 18 forward whereby the bell crank 17 is moved in a reversedirection to that just described and the hold down is brought inward andlowered in a manner described in my prior patent. The relation of thecam 28 to the cams for operating the pincers is such that the downwardmovement of the hold down occurs while the pincers are performing theirupward movement, by virtue of which action the length of this movementis materially increased. This vertical movement of the ,hold down isgenerally desirable only while the single lasting operation at the shankis being performed, and, therefore, the cam roll 26 should be shiftedback to its inactive position after the completion of a single lastingoperation, so that the hold down will thereafter remain in its normalposition. Preferably the roll 26 is shifted back on to the plane rearface of the cam disk 27 after the updraw movement of the pincers hasbeen completed. This is accomplished by a tappet cam (Figs. 1 and 4)carried on the periphery of the cam disk 27 in such angular relation tothe cam 28 that it will engage and depress the arm 32 of the three armedlever hereinbefore described at a convenient time after the roll 26 hasreached the upper end of the incline forming the cam 28. The depressionof the arm 32 slides the lever inward toward the driving shaft and actsalso to elevate the connecting rod and, through the rock shaft 36, thehandle 38. The parts hereinbefore described are thus all returned totheir original position, and are not again brought into use unless theoperative finds it desirable to again utilize a long pull.

Power is supplied to the machine to rotate the driving shaft 6 throughthe fast pulley to (Fig. mounted on the outer end of the power shaft llsuitably journaled in bearings formed at the base of the column whichsupports the lasting head. Besides the fast pulley 40 there is the usualloose pulley 42.

Two sets of driving connections run from the power shaft 11 to thedriving shaft 6, one set for driving the shaft 6 at slow speed and theother set for driving said shaft ata high speed, which is the normalspeed of the machine. The slotv speed driving connections are controlledby a friction clutch on the driving shaft 6, while the high speedconnections are controlled by another friction clutch on the power shaftll.

Considering first the slow speed driving mechanism the power shaft 41has secured thereon a spiral gear 43 (Fig. 2) which has intermeshingtherewith, and drives, a second spiral gear 44 mounted on the lower endof a vertical shaft 45 which is stepped in a suitable hanger 46 securedto the base of the column as shown at 47 (Fig. 2). The upper end of thevertical shaft 45 (see Figs. 1 and 4) is journaled in a hanger 48mounted on the machine frame and carries a worm 49 which meshes with anddrives a worm gear 50 (Figs. 1 and 9) loosely mounted on the drivingshaft 6. As the hanger 48 is not vertically above the hanger 46 theshaft 4-5 is formed in three parts and the central part is connected tothe end parts by universal joints 51. These connections provide for acontinuous rotation of the form wheel 50 from the power shaft 41. Theinner end 511 of the worm 50 is connected by an ordinary toothed splitjoint 52 (Figs. 3 and 9) to the outer end of the hub 53 of the movablemember 54 of the friction clutch, the

other member 55 of which is formed on the rear face of the usual drivingpulley 56 found in hand method lasting machines of the type illustrated.The two clutch memhers and 55 are engaged, so as to cause rotation ofthe shaft 6, under power supplied from the worm 50 by wedging these twomembers together in the usual manner. The wedge is shown at 57 (Figs. 1,3 and 9) and is bifurcated as usual, straddling the driving shaft 6."The wedge bears with its oblique surface upon a transverse plate 58carried by a sleeve 59 surrounding the clutch 52 and secured to the hub53 in the usual manner to permit rotation of the hub within the sleeve,as clearly shown in Fig. 9. The vertically movable frame 60 whichcarries the wedge 57 is provided with a pair of side wings G1 whichextend forwardly and each of uhich carries a roll 62 arranged to bear onthe forward or under side of the plate 58. l l hen the wedge 57 ispulled down, by means presently to be described, it wedges the plate 58forward, opening the slip joint slightly, and this plate, through itsconnection with the hub 53, forces the part 54 of I the friction clutchinto engagement with the part 55 which rotates the pulley 56 and,

through it, the driving shaft 6. Such rotation of the driving shaft willcontinue until the clutch 5455 is-disconneeted.

Power for the high speed drive is obtained 7 from a friction clutch,comprising a mov- 4 able friction disk 63 (Fig. 2) carried on the hub ofthe pulley 64 loosely mounted on the power shaft 41 and adapted to beforced into engagement w1th the second frlctlon disk 65 mounted forrotation with the shaft 41. A sliding sleeve, as shown in the patentsreferred to, is connected to the forward end of the hub of the pulley64, and

66 at its forward end.

disks are brought into engagement with each 7 other by forcing a wedge67 past the face 66 and thus moving the disk 63 longitudinally of theshaft 41. The spring 68, having one end attached to the sliding sleeveand its other end attached to the machine frame, keeps the Wedge 67 andface 66 in contact with each other. A belt runs from the pulley 64 onthe shaft 41 over the pul ley 56 on the shaft 6 sothat the shaft 6 isdriven directly fromthe shaft 41 when the clutch members 63-65 areengaged.

The wedge 67, through which the high speed clutch is connected, is movedin a direction to connect said clutch by means of a treadle 69 (Fig. 2)pivoted at 70 in the 7 lower portion of the machine column. This treadleis pivotally connected at its inner end to the lower arm 71 of thetoggle, the upper arm 72 of which is pivoted to the wedge 67. Thepurpose of this toggle will presently be explained, it being sufficientnow to say that when the slow speeddriving mechanism is not in use thetoggle is normally unbroken, that is, it is in the position shown inFig. 2, and erforms the function of a rigid rod by whlch the wedge 67may be moved.

The wedge 57, the movement of which causes engagement between the clutchmem bers 54-55 on the shaft 6, is operated from a treadle 7 3 (Fig. 2),also fulcrumed on the The functionof the recessed rod 77 will beexplained after describing the remainder of the connections foroperating the wedge 57.

To the upper end of the push rod 75 there.

is secured a collar 79 having an ear to which is pivoted the lower endof a vertical link" 7 80, the upper end of which link is pivoted to theforward end of a lever 81 fulcrumed on a pin 82 Figs. 1 and 4) journaledin a hanger 83 (Fig. 4) depending from the frameof the machine. The rearend of the lever 81 has pivoted thereto the lower end of a vertical link84, the upper end of which is in turn pivoted to the lower end of asecond push rod 85 (Fig. 1), the upper end of which carries thevertically movable frame 60 which supports the wedge 57.

Coiled around the push rod 85 is a spring 86 seated between the frame60-and the upper end of the vertical bearing within which the push rod85 slides. This spring.

normally maintains the wedge 57 in its upper position as shown in Fig.1, and when the treadle 73' has been depressed, it, owing to thedownward movement of the push rod 85, is compressed.

The purpose of the recessed rod 77 forming an extension of the push rod75 will now be explained. The movement of the rod 77 controls the brakefor stopping the machine at a predetermined point in the cycle ofoperations. Referring now to Figs. 1 and 3, the brake shoe 87 is shownas being mounted on the end of an arm 88, is pivoted on the machineframe and is provided with a suitably mounted spring 89 which tends tomaintain the brake shoe in contact with the inner surface of the rim atthe forward side of the pulley 56. The brake arm 88 is provided with alaterally projecting pin 90 (dot-ted lines Fig. 1) which is engaged by agroove formed by a pair of ears 91 (Figs. 1 and 2) projecting laterallyfrom the rod 77. By means of this connection when the rod 7 7 is movedupwardly by the upward movement of the push rod 75 it carries the brakearm 88 upwardly also and removes the brake shoe 87 from contact with itsbreaking surface leaving the pulley 56 free to rotate. It will beobserved that between the upper end of the unreduced portion of the pushrod 75 and the lower end of the recessed rod 77 there is a space whichgives time for effecting an engagement of the clutch members 54-55 atabout the same time that the rod 77 effects a disengagement of the brakeshoe 87 from the pulley 56. The extreme upper end of the rod 77 isprovided with two central ears 92 forming a groove within which isengaged a pin 93 projecting laterally from a lever 94 pivoted to theframe of the machine at 95 (see Fig. 3) which lever carries a roll 96adapted to run upon a circular cam track 97 formed on the forward faceof the pulley 56. This cam track is provided with a depression 98 andwhen the roll 90 rests in this depression, as shown in Fig. 3, the brakeshoe S7 is permitted to be forced by its springinto engagement with theriln of the pulley 56 to stop the rotation of the driving shaft. Aslong, however, as the roll 96 runs on the remaining, circular portion ofthe cam track 97, the brake shoe S7 is positively held in its raised andinoperative position. It is thus seen that when the treadle 73 isdepressed to throw in the slow speed driving mechanism the brake shoe S7and roll 96 are simultaneously raised by the upward movement of the rod77, and that the roll 96 is immediately caught, by reason of the rotation of the pulley 56, on the higher portion of the cam track 97 andmaintains the brake shoe 87 out of engagement with its braking surfaceuntil a complete revolution of the driving shaft has been made, that is,until the depression 98 again reaches the position shown in Fig. 3, atwhich time the brake again becomes active and, one or the other of thefriction clutches having been disconnected, stops the machine.

Means is provided for locking the wedge 57 in its lowered position sothat it is unnecessary for the operative to retain his foot on thetreadle 73 after it has once been depressed. Referring now moreparticularly to 1 and l, the rod 85 is provided with a pin 99 extendinglaterally through a slot in the forward side of the vertical bearing forthe rod and as the rod is moved downward to seat the wedge 57 in itsclutch operating position this pin is moved from its full line to itsdotted line position shown in ig. 1. As it moves downward it passesbeyow the end of a locking wedge 100 which is pivoted on a pin 101projecting from the frame and as soon as the pin 99 reaches its lower ordotted line position, the wedge 100 is drawn by means of the spring 102from its full line to its dotted line position shown in Fig. 4. While inits dotted line position the wedge 100 acts as a strut to prevent anyupward movement of the rod 85 under the influence of the spring 86,which, having been compressed, tends constantly to raise the rod andrelease the clutch 54e55.

As already stated the long slow pull on the upper is necessary only inthe lasting movement at the shank or waist of the shoe, and,furthermore, it is not essential that this slow speed of the machine becontinued after the updraw movement of the pincers has been completed.Means, is, therefore, provided which will release the wedge 57 to theaction of the coiled spring 86 so that the clutch 5l55 will bedisconnected and the slow speed of the machine thrown out, preferably,after the completion of the u )draw movement of the pincers. To this encthere is provided on the flange at the rear side of the pulley 56 atappet cam 103 shown in full lines in Fig. 1, and in dotted lines in rFig. 1, which cam is so located with refer ence to the angular movementof the pulley 56 that it will throw the connections, now to bedescribed, in a direction to withdraw the wedge block 100 from itsdotted line to its full line position in Fig. 4, and permit the rod 85to move upwardly under the influence of the spring 86 thus disconnectingthe wedge 5455. Still referring to Figs. 1 and 1, the shaft 82 formingthe fulcrum of the lever 81 has secured to its right hand end, viewingFig. 4, a vertical lever arm 104:, which is connected by a link 105 tothe lower end of a lever 106 centrally pivoted on the frame of themachine. The upper end of the lever 106 is provided with a laterallyprojecting pin 107 which engages a vertical groove formed in the hub ofa lever arm 108. This hub is slidably mounted upon a horizontal pin 109having a bearing at its forward end in a bracket 110 (Fig. 1) and at itsrear end in the side of the vertical bearing for the rod 85. The lever108 carries a roll 111 adapted to bear on the inner surface of the rearflange of the pulley 56 and is held in contact with said flange by meansof a suitably connected coiled spring 112 (Fig. 4). When the pivot 82 ofthe lever 81 is rocked by the movement of said lever, in drawing thewedge 57 downward, the lever arm 10a is swung to the right, viewing Fig.1, which, through the connections described, acts to slide the hub ofthe lever arm 108 to the left along the pivot pin 109 and move the roll111 inward into the path of movement of the tappetcam 103. which, asshown in Fig. 1, is only of about one-half the width of the rear flangeon the pulley 56, and unless the roll 111 is moved inward will pass saidroll, without engagement therewith, as the pulley rotates. After theroll 111 has been moved forward, however, itis engaged by the tappet cam103 and lifted. As the hub of the lever 108 is loose upon its pivot pin109, the lifting of the lever arm under the influence of the tappet cam103 would ordinarily have no effect upon the mechanism, but extendingrearwardly from said lever arm 108 is a horizontal pin 1112 whichengages a groove or recess in a second upwardly projecting arm 113, alsoloosely mounted on the pivot pin 109, and moves said arm to the right,viewing Fig. f. This arm 113 is provided at its upper end with alaterally projecting pin 11 1 (see dotted lines in Figs. 1 and 1) andthe movement of this arm to the right, as described, causes this pin toengage a laterally projecting ear 115 formed on the rear edge of thewedge block 100. The movement of the arm 113 under the influence of thetappet cam 103, therefore, forces thewedge block 100 from its dottedline to its full line position in Fig. 4, thus removing it from abovethe pin 99 and permitting the rod 85 with its wedge block 57 to beraised under the influence of the coiled spring 86. As the wedge 57moves upward the engagement of its oblique face on one side of the plate58, and the rolls 62 on the other side of said plate, act on the platein a manner to positively withdraw the movable clutch member 5 1 fromits 00- operating member 55 and thus disconnect the slow speed drivingmechanism from its control of the driving shaft 6.

It will be observed that the machine is not now stopped because the roll96 (Fig. 3) is, at the time of the disconnection of the clutch 5455,riding upon the high part of the cam track 97 and thus holding the brakeshoe 87 from engaging its braking surface. It is desirable, from thispoint in the operation of lasting the shoe, to run the machine at itsnormal, or high, speed and, therefore,

6365 to the high speed driving mechanism in such time relation to thedisconnectionof the slow speed driving mechanism as will continue theoperation of the machine without break. Such a change from the slow tothe high speed is preferably performed by the machine itself,automatically, without any attention on the part of the opera tive. Inthe form of the invention illustrated in the drawings, after suchautomatic connection, the high speed will'continue until the completionof one revolution of the driving shaft 6 at which time the roll 96 willenter the depression 98 in the cam track 97 thus lowering the rod 7 7,permitting the brake shoe 87 to engage the braking surface and, throughconnections presently to be described, lowering the wedge 67 anddisconnectingthe high speed clutch 6365. After such disconnection onelasting operation will have been performed, and further lastingoperations may be performed by merely depressing the high speed treadle69 which will cause the machine to be at the high speed without anyreference whatever to the slow speed driving mechanism.

The means for automatically drawing the wedge 67 (Fig. 2) upward so asto cause an operative engagement of the two parts 63 and of the highspeed friction clutch is shown best in Figs. 1 and 1. Referring to thesefigures the drive shaft e15, it will be remembered, is continuouslyrotated from the power shaft 41 and on this shaft 15 there is mounted aface cam 116. This cam is normally disconnected and loose on the shaft15, but it may be connected to rotate with the shaft by the operation ofa Horton clutch, which is connected with the cam and indicated merely bythe ring 117 and the cage tripping lug 118 shown in full lines in Fig. 1and in dotted lines in Fig. l. The pin 114: at the upper end of the arm113 is extended sufficiently so as to pivot thereon one end of a link119, the other end of which link is pivoted to the vertical arm 120 of abell crank lever fulcrumed on a pin 121 held in bearings on the machineframe. The horizontal arm 122 of this bell crank lever bears against thelug 118, and while so engaged maintains the clutch disconnected. In thisconstruction when the lever arm 108 is raised by the tappet cam 103 themovement of the connected lever arm 113, to the right in Fig. 4:, drawsthe link 119 to the right also and thus moves the bell crank arm 122 outof engagement with the lug 118. This permits the Horton clutch toconnect the cam 116 with the shaft 15 and cause this cam to rotatetherewith. The surface of the cam 116 is engaged by a roll 123 at therear end of a horizontal lever 1% having a hub secured to one end of ashort horizontal rock shaft 125 journaled in the machine frame (see Fig.t). A second lever 1124i has a hub secured to the other end of the shaft125 and extends forwardly. From the free end of the lever 112s theredepends a link 126 (Figs. 1 and 3) the lower end of which link ispivoted to a sleeve 127 clamped on the upper end of a vertical rod 128(Figs. 1, 2 and the lower end of which is seated in a socket at theupper end of a member 129 which straddles the power shaft 11 and carriesthe wedge 67 at its lower end.

By means of the construction just described, it is seen that when theslow speed clutch 5a155 is disconnected the cam 116 is connected to berotated by the shaft 45 so that the cam 116 operates immediately todepress the outer end of the lever 1124:, raise the rod 128, and thusforce the wedge 67 against the complemental oblique surface (36 toconnect the clutch for the high speed driving mechanism. By thismechanism the high speed is immediately thrown into operation whencontrol of the driving shaft by the slow speed mechanism, is lost.

In order to prevent the operative from again throwing in the slow speedmechanism while the high speed mechanism is operating the machine, therod 7 5 (Fig. 2) is provided, intermediate its length, with a togglecomprising arms 130 and 131. To the knuckle of this toggle there ispivoted. one end-of a link 132, the other end of which is pivoted to thelower end of a lever arm 133 (Figs. 1, 2 and 1) the upper end of whichlever is secured by a set screw to the rock shaft 125. Thus when theshaft is rocked by movement of the lever 124:, the lever arm 133 ismoved to the left in Figs. 1 and 2, which breaks the toggle 130131, asshown in dotted lines in Fig. 2, and renders the rod inoperative toactuate the slow speed driving mechanism.

in the breaking of the toggle 130-131, when the rod is raised by thespring 86 to remove the wedge 57 from its operative position anddisconnect the slow speed clutch, the rod 7 5 drops to the position itoccupied befor the treadle 73 was depressed. The rod 77, however, doesnot drop as this rod is held up by the hearing which the cam roll 96 hasupon the cam track 97.

It will be observed that after the cam 116 has rotated a suflicientangular distance to remove its acting portion from the roll 123, the rod128 would drop by gravitation and disconnect the high speed clutchunless means is provided for locking said rod 128 in its raisedposition. The rod 77, which has just been referred to as remaining inits raised posit-ion, is, together with certain mechanism new to bedescribed, utilized for holding the rod 128 raised and thus maintainingthe high speed clutch members 6365 in operative engagement. The settingof this locking mechanism for the rod 128 starts with the upwardmovement of the rod 75 in connecting the slow speed clutch. Referring toFigs. 1 and 5, the collar 79 is provided with a lug 134 to which isconnected a vertical push rod 135 which projects upwardly from the lugand through a guide hole in a shelf 136 projecting laterally from acollar 137 secured to the lower end of the rod 77. The collar 137 haspivoted thereon a latch 138, the lower edge of which is adapted to beengaged by the rod The latch 138 is provided with a laterally extendingfinger 139 which bears upon the upper side of a lug 14:0 secured to therear side of a wedge block 14.1 pivotally mounted upon a collar 142clamped at' the upper end of the rod 128. The latch 138 and the wedgeblock 1 11 are adapted to swing in different planes past each other. Onthe first part the upward movement of the rod 1'5 before its upper endengages the lower end' of the rod 77, the pin 135 is carried upward tothe position shown in Fig. 6, and in this movement moves the latch 138upward, but not out of engagement with the lug 110. A torsion spring1112, coiled about the pivot of the wedge block 1&1, tends constantly toforce said wedge block inward to a position over the shelf 136 andmaintains the lug 1 10 in conact with the latch 138. After the upper endof the rod 75 has engaged the lower end of the rod 77, the latch 138 andshelf 136 are carried upward by the upward movement of the rod 77 indisengaging the brake which upward movement disconnects the latch 138from the lug 140 and permits the spring 1142 to move the wedge block1+i1 into contact with the edge of the shelf 133, as shown in Fig. 7.The locking mechanism for the high speed clutch remains in he positionshown in Fig. 7 until the rod 128 is moved npvmrdly by the lever 1.12%.'i iis upward movement of the rod 128 lifts the wedge block 1&1 to aposition above the shelf 136 and permits its spring 11 12 to move itinward to the dotted line position shown in F 8 where its lower edgebears upon the shelf 136 and causes it to act as a strut to preventdownward movement of the rod 128. At the same time, after the edge block1 11 moves in over the shelf 13G, lug 14.0 by engaging the under side ofthe latch 138 pushes this latch to the dotted line position shown inFig. 8. A pin 1138 limits the inwarc. movement of the latch and wedgeblock.

As hereinbefore described, the machine stops after a single revolutionof the driving shaft 6, that is, when the roll 96 (F ig. 3) drops intothe depression 98 formed in the cam track 97. The dropping of the roll93, under the influence of the brake spring 89, pushes the rod 77downward and permits the brake shoe 87 to engage its braking surface tostop the machine. The lowering of the rod 77 with its shelf 136 permitsthe rod 128 to drop and by lowering the wedge (57, disconnect the twomembers (5365 of the high speed clutch.

In order to return the wedge block 1 11 to the position shown in Fig. 5,so that it will be proi ierly positioned for the next depres sion of theslow speed treadle 73, the shelf 136 is provided with an upwardlyextending trip rod 113 (Figs. 5 to 8) which as the rod 7 7 is raisedengages, with a beveled end provided for this purpose, a spring block11-1 attached to the frame of the machine, and removes it from contactwith a pin 14:5 carried by an upwardly projecting tail piece 146,attached to the wedge block 1&1. This movement of the spring block 1 1 1permits the wedge block 14 1 to move inward against the side of theshelf 136 (as in Fig. 7) as it permits free movement of the tail piece1l 6 to the left. ii hen the wedge block 1&1 is raised and swung to theright, into the dotted line position of Fig. 8, the tail piece 1&6 isswung, by the lug 1 10, to the left into its dotted line position shownin the same figure where it rests above the wedge piece 1%.

Vhen the rod 77, and with it the rod 128, is lowered the wedge block 111is tipped about its pivot to the left (Fig. 8) by reason of theengagement of the pin 115 with an oblique surface at the upper side ofthe spring block 1%. This camming action on the pin 11?) winds up thespring 11 l-2 and brings the parts back to the full line position ofFig. 8. At the time the parts reach this position the beveled end of thetrip rod L13 is released from the spring block 116 and this block thenkicks the pin 1-15 and forces the lug 1 10 outwardly beyond the end ofthe latch 138. This permits the latch lock 138 to drop by gravity pastthe lug 1'10 and the parts finally to reassume their original positionas shown in Fig. 5.

From the foregoing description it will be seen that the single lastingmovement which has occurred between the time of the depre. sion of theslow speed treadle 73 and the disconnection of the high speed clutchmembers 6365 has been at two speeds. The slow speed driving mechanismhas been operative during the updraw movement of the pincers and thehigh speed mechanism has been operative for the remainder of the lasting movement which includes the tacking of the upper in place. For theremainder of the lasting operations around the shoe, except for thesingle lasting movement at the opposite side of the shank, or waist, itis possible, and desirable, to utilize the high speed driving mechanismalone. In order that this mechanism may be used, without first throwingin the slow speed mechanism, the collar 127 on the rod 128 is providedwith a shelf 1 17 which, when the machine is at rest, engages the lowerside ofthe shelf 136 as shown in Figs. 1 and When it is desired tooperate the machine through the high speed mechanism alone, it is merelynecessary to depress the high speed treadle ($9 which will elevate thewedge 67, connect the high speed clutch and, through the engagement ofthe shelf 1 17 with the under side of the shelf 136, raise the rod 77 soas to remove the brake shoe 87 from its braking surface and also raisethe roll 96 so that on rotation of the pulley 56 it will be caught andheld in its r; ised position by the cam track 97. So long as theoperative maintains the treadle 59 depressed, the machine will run atits high speed, but as soon as he removes his foot from the treadle themachine will again stop when the roll 96 reaches the depression 98.

The purpose of the toggle '71-7 2 in the connection between the highspeed treadle (39 and the wedge 67 will now be explained. The link 72of-this toggle is provided with a lug 1 18 (Fig. 2) which is adapted tobe engaged at its under side by a second lug 1 19 formed on the rod 7 awhich is connected to the slow speed treadle 7 3. When the slow speedtreadle 7 3 is depressed, to run the machine initially at slow speed,the upward movement of the lug 1 19 moves the lug 1&8 in a direction tobreak the toggle 71-72 and render the high speed driving mechanismunresponsive to a depression of the high speed treadle 69. This is asafety device similar to the toggle 130131 which prevents the operativefrom throwing both driving mechanisms into operation at the same time.The toggle arm 71 is also provided with a lug 150 (Fig. 2) the lowerside of which is adapted to be engaged by the inner end of a toggleresetting treadle 151. The purpose of this treadle 151 is to straightenthe toggle 7172, if necessary, prior to the depression of the treadle 69for driving the machine by the high speed alone.

In operating upon some styles of shoes, it is desirable to run themachine at a slow speed during several lasting movements instead oflimiting the time of operation of the slow speed to the operation of asingle lasting movement only as in the case when the mechanism isconnected as illustrated in the drawings. in order to provide for suchan operation of the machine it is merely necessary that a simpleadjustment be made, that is, a disconnection of the operative connectionbetween the slow and high speed trains of driving mechanisms sothateither one may be used without the other and solely under control oftheir respective starting treadles. Provision is made for suchdisconnection of these two driving mechanisms by making the two arms ofthe bell crank lever 120122 of two separate parts and securing the hubof each part to the pin 121 by means of a set screw as shown in Figs. 1and 4. When it is desired to disconnect the two driving mechanisms theset screw securing the arm 120 to the pin 121 is loosened so that themovement of this arm, caused by the reciprocation of the link 117, isidle, and, therefore, fails to impart movement to the arm 122. The arm122 is, therefore, never removed from its position shown in Fig. 4, and,consequently, the Horton clutch 117 never becomes operative. It will beobvious that with the lever arm 122 disconnected from the pin 121, solong as the treadle 7 3 is held depressed maintaining the pin 99 in itsdotted line position, Fig. 4, the machine will continue to run at theslow speed, because, as the toggle 130131 is not broken the pressure onthe rod 75 prevents the roll 96 from descending into the depression 98in the cam track 97 to apply the brake, and the reciprocation of thewedge block 100 under the influence of its spring 102 and the tappet cam103 is ineffective. lVhenever the treadle 73 is released the machinewill stop as soon as the wedge block 100 is removed from above the pin99 by the tappet cam 103, the momentum of the pulley 56 not beingsufficient, when driven at the slow speed, to overcome the inertia ofthe parts and the resistance due to the setting of the driver spring.After the cessation, at the will of the operator, of the slow speeddrive, the high speed treadle 69 is depressed and the lasting of theshoe continued at the high speed.

If it is found that under some factory conditions the machine does notstop immediately, without the aid of the brake, when the slow speedclutch is disconnected, the brake may be utilized by means of a furthersimple adjustment as follows. By loosening the bolt which secures thecollar 137 (Fig. 1) to the rod 77 this rod may be turned within thecollar. By turning the rod 77 in a clockwise direction through 90, theears 92 are removed from engagement with the pin 93. This rotarymovement of the rod 77 does not, however, disengage the pin 90 from thegroove formed by the ears 91, as these cars are so proportioned (seeFig. 1) as to retain their engagement of the pin 90 when the rod 77 isso rotated. After rotating the rod 77, as described, the collar 137 isagain clamped thereon and, thereafter, whenever the slow, or the high,speed treadle is released the brake shoe 87 will immediately engage itsbraking surface, for the reason that such brake shoe is re moved fromits former control by the cam track 97. It is, also, considereddesirable by some operatives to run the machine for one, or a portion ofone lasting movement only, at the slow speed and then connect the highspeed by means under control of the operative, that is, omitting theautomatic change of speed by means of the cam 116 (Figs. 1 and 4t) andthe mechanism operated thereby. A simple adjustment, only, is necessaryto cause the machine to operate in this manner. As shown best in Fig. 4,and as here tofore described, the hubs of the levers 124k and 1124c aresecured to the rock shaft 125 by set screws. By loosening the set screwfor the lever 1121 any movement of the lever 12% will fail to raise thepush rod 128 and connect the high speed clutch 6365. Now when the tappetcam 103 releases the pin 99 by moving the wedge block 100 from above itand at the same time causes the cam 116 to rotate, the slow speed clutchwill be disconnected and at the same time the toggle 130- 131 will bebroken. This will cause the treadle 73 to drop under the continuedpressure of the foot of the operative. This movement of the treadle 73acts as a signal to indicate to the operative that the slow speed clutchhas been disconnected and he at once slips his foot over on to the highspeed treadle 69, and toggle resetting treadle 151, by a depression ofwhich the high speed clutch is connected and the machine continues atthe high speed as long as the treadle 69 is retained in its depressedposition. A spring 1123 (Figs. 1 and 4), connecting the lever 12st witha lug on the frame holds the roll 123 in contact with the cam 116, andin the preferred manner of operating the machine this spring supplementsthe action of the brake shoe spring 89 in causing a downward movement ofthe lever 1124: to move the roll 123 upward and reset the toggle130-431.

As the operation of the machine has already been fully described inconnection with the detailed description of its various features it isbelieved necessarv only to add that the combined slow updraw movement ofthe pincers and downward movement of the hold down affords anexceedingly effective action on the upper at the shank, closelysimulating the nature of this pull when given by hand and that this slowmovement is continued only so long as is necessary and desirable.
